A extremely handy script that allows you to have multiple domain names registered to one (1) IP address and have them all redirected to a sub site of another. For example, you register search.yourdomain.com, chat.yourdomain.com and scripts.yourdomain.com. Instead of having to use 3 extra IP's, you can redirect to yourdomain.com/search, yourdomain.com/chat and yourdomain.com/scripts.
